HANGING- THE FORE-PLATES IRON-ROLLING- MACHINERY.

Specicaton of`Letters PatentNo. 10,524, 'dated Ilebruary4 14, 1854'.

To all whom t may concern.'

Be it known that I, JACOB REEsE, of Sharon, in the county of Mercer andStat-e of Pennsylvania, have invented a .new and useful Improvement inMachinery for the Rolling of Iron; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the annexed drawings, forming part of this specification,wherein- Figure l, is a perspective view of that part of the machineryof a rolling mill to which my improvements are to befapplied, showingthe fore plate in its place in front of the finishing rolls, and theupper roll, b, not connected by the coupling with the shaft of the rolld. Fig. 2, is a perspective view of the same machinery, the uprights ofthe frame work being removed so asvto show Vthe details of the machinerymore distinctly, the fore plate being thrown back from the rolls; thescouring board being in place, between the rolls, and the rollrb beingconnected by the coupling with the shaft of the roll a. Fig. 3,represents av self `supporting coupling. Figs. 4, 5, 6 and 7 representthe several parts of Fig. 3` detached.` Fig. 8 rep-k resents the oldkind of coupling. Figs. 9, 10, and l1 represent the several parts of theold kind of coupling, detached.

In the several drawings the same letters refer to similar parts of themachinery.

My invention and improvement consists in connecting the fore-plateto theframe work which sustains the rollers, by adding to it arms which workon a bar or brace, as a center, thereby enabling the fore-plateA to bedrawn away from the rolls or brought to its place again by simplyturning it on its center and avoiding the delay of re-V moving theguides, the fore-plate and the rest bar, as is necessary on the oldplan, whenever the rolls are to be scoured..

In order to explain fully the nature of my invention, it will benecessary to explain the present arrangement of the machinery l used forrolling and finishing, and the difficulties which my improvements aredethe frame a and a where it is connected withthe neck of another roll dtoV which roller ai, or others similarly connected with it, motioniscommunicated from the steam engine or other motive power. The couplingshown in the drawings as connecting the necks of the rolls b and d is ofthe ordinary kind and is thus constructed. rIhe ends of the necks of therolls to be connected arey made of similar diameter and shape, beingsquared or of anyusual and convenient shape, other than circular.Between the extremities of these rolls is placed a short connectingpiece e, which is of vsimilar diameter and shape to the ends ofthe necksof the rolls b and d.

Two rings or boxesof iron f, f' are placed on'l this co-n.

necting piece, the .inner surface of which is a counterpart of the shapeof j the necks of the rolls b and al', and which V fits said necks, andconnecting piece, ex-

actly, andv yet will: slide back and fort-h from the necks to connectingpiece e. Now when..

it is desired to couple or connect theV rolls b" andai the coupling justdescribed 'is' placed between the necks` of the rolls to be rgearedtogether, and the rings or 'boxes f and f are slid apart along theconnecting piece e, so as to cover the joints between the plece @,andthe ends of therolls b andai.

.The rings are kept-fat the right distance apart by a strip of wood Voriron g, Vtied laround the connectingl piece e. v The rolls` b and darethus so connected 'that therevOlu-V tion' ofthe roll d" carries with itthe roll Z2', butv if it be desired to disconnect them, it isnecessary-to yremove Vthe separator g, and draw the rings f, f, Vtowardeach other on the connecting Vpiece e, which leaves the couplingwithoutany support, Aso that .it

'must be entirely lremoved until it is desired,

again to connect the' rolls b and d. V'Iodo all this requires the wholemachinery to be stoppedwhich causeskgreat loss of time.

The upper finishing roller, 5,(is kept in its place o-ver the lowerlroller b', by the bearings or half journal` boxes 71 the journals offthe roll b havingno lower bearing, as-it rests on the roll b', andwhenin use itis not in` gear withfany other roll", but is turnedn asv afriction roller by its contact with the lower roller, or with the ironpassing over the lower roller. It is necessary-that the Lipperl rollershouldv not be geared to any other shaft or roll, so that it may revolveevenly WithV the lower rollerY b, because if the upper e, f, g, beforedescribed, but as the coupling roller had motion independent of what itobtains from Contact with the lower roller and there was the slightest4variation ind-V would be about 8 times a day. This is do-nel by placingthevscouring board z', with oil Vand emery upon it, between the rolls band b', and causing them stillto revolve. (See Fig. 2.) Now the momentthe scouring board z', is placed thus between the rolls, the friction ofthe rollb on the roll b, by which the latter was turned, ceases, and theupper roll Z) will stand still unless it be con- ,nected with the shaftof a working roller (Z, along side of it. This has 'heretofore been doneby means of the ordinary coupling has to VYbe removed and brought backeach time, and the machinery has to be stopped it becomes a serioushindrance. This is obviated by the use of the self sustaining couplingshown in detail in Fig. 3, and Figs.

4, 5, 6, 7 le is the box (of the shape shown in Fig. 7 and hollowthroughout), one end being shaped to fit over the neck of the roll andthe other end having a cylindrical bore, Y

to receive the end of the spindle Z a key m which passes through the box7e at right angles to its axis serves toseparate the neck of the rolland the end ofthe spindle, and to keeppthe box 7c, in place, thusanswering the purpose of the spreading block goin the ordinary coupling.The box 7c has a groove cut inside of it along the cylindrical bore, toreceive a `corresponding rabbet `on the spindle. The spindle Z is acylindrical shaped piece, suficiently long to connect the ends of therolls to be coupled. The rabbet n forms a key, which 'tting into thegroove in the Vbox k, causes the spindle to revolve with the rolltowhich the box is attached. The other end of the spindle is insertedina cylindrical bore in the box 0` which has crab lugs,'to fit into thelugs of the sliding crab p VThe box-0, has also a key m', similar tothat'in the box'k, to keep the box in its place. The rabbet or key n.does not extend quite far enough `on the spindle to reach the box o, butapproaches near to it; the spindle therefore turns freely in the box o,(by which and the box 7a it is supported) without carrying'the box 0, orthe roll to which it is attached, with it. The sliding crab p which haslugs to ucorrespond with those on the box o, has a cylindrical borethroughout so as to slide evenly on the Aspindle and has a groove toreceive the key 1t, so that the crab cannot turn around on thespindle,.but is carried around with it.

Now when the several parts are inthe po- Vone frame to the other.

time.

sition shown in Figs. 1 and 8, the spindle and crab are supported by theboxes Zc and Vo, and the roll to which the box '7c is attached canrevolve, (and with it the spindle Z and crab p) without affecting thebox' 0 or its roller Z2, and at the same time the spindle Z,

.by enteringthe bore of the box o, within which it turns freely,supports the roller b, without the use of a bearing under the journal ofthe roll b, which would otherwise be necessary. Now if it is desired tocouple the roll Z9 withthe roll Z,it is done by simply sliding the crabp until its lugs interlock with those of the box 0. VThe rabbet 'nextends so far Vthat the crab 29 is still over it and as the spindletherefore cannot revolve` without carrying with it the crab y), which isnow interlocked with the box o, the coupling is complete. :Theconnection can be at once brokenby sliding back the crab p far eno-ughto release the lugs of the` box 0.

The advantage of this form of coupling is that it is sustained withoutany additional bearing between the coupling and one of the rolls to beconnected, as is ordinarily required where couplings are used, and isnot detached from the rolls by the act of throwing them in or out ofgear, and that it can be used without-any stoppage `of the machinery.

In the drawings Figs. l and 2 g is the fore-plate, and 1, r, are theguides, placed before the rollers, to aid in feeding in the iron to berolled. Fig. l, shows the foreplate and guides in their right place. Thefore plate is usually inserted in grooves in the frames a, a whichsupport the rolls,

and lies upon a rest bar, which extends from y In orderto insert theboard z' for scouring'the rolls, it is necessary on the old plan ofconstruction to stop t-he machinery, and unscrew the guides from "thefore-plate, and remove the fore plate and rest bar. p This `is `atedious and diHicult job, andhas moreover to be done about eight timesaV day and causes a very 1 serious expenditure `of` labor and loss ofserving as a brace tothe frames, and making the pivot or center on whichthese arms turn. I also add a lug u, to each side of they fore plate g,which, when the fore plate is in the position shown in Fig.l l, restagainst the outside ofthe frames a, a and act as stops to prevent thefore plate being drawn tooclose to the rolls when the iron is passingover it, through the rolls. When itis desired to insert the scouringboard between the rolls all that is necessary is to turn the fore plateon its arms, thusldrawing it away All this I `savelby my arrangementfrom the rolls as seen in Fig. 2. It may readily be replaced again, bysimply-raising it up, When the operation of scouring is complete, andthe rolls b and d (which had been connected by the coupling for thepurpose of scouring, to impart motion to the roll ZJ, which hadotherwise been locked by the action of the scouring board) are nowdisconnected by sliding back the crab p and the machinery is again ittedfor use. Thus the operation of scouring the finishing rolls isaccomplished Without stopping the machinery for a single moment.

The other parts of the drawings are the usual appendages to similarmachinery in a.

rolling mill, and need not be particularly described.

Having thus described my improvements in machinery for rolling iron andother metals What I claim as my invention and desire to secure byLetters yPatent is not` the scouring of rolls as described in the.v

foregoing specification, nor yetthe coupling of the upper roll When therolls are to bel scoured and uncouplingit When they are in use. But lWhat I do claim as my invention is'-` The hanging thev fore plate of arolling vmill on centers, placed either above orv below the level of therolls, by adding arms to the fore plate, Working on a bar or onpivots,r`

for the purposeof removing the fore plate out of lthe Way When the rollsare to be scouredlvvithout detaching it fromthe frame ofthe mill,substantially in the manner here- 35 Y
